In this study, fibre morphology of microwave-treated oil palm trunks (Elaeis guineensis Jacq.) was studied. Thirty years old palm trunks (OPT) were selected, felled and divided into peripheral, middle and inner zones. Only the basal portion of the OPT was used to reduce variability of sampling. Microwave treatment of the OPT samples were conducted by using a domestic microwave oven operating at 2.45 GHz and with maximum rated power output of 950 watt. The samples were microwave-treated at four different power intensities of 950, 700, 500 and 300 watts and for four different exposure durations of 5, 10, 15 and 20 min leading to a total six varying combinations of power and exposure period. The untreated OPT sample was used for comparison purpose. The fibre length, fibre diameter, fibre lumens diameter, and fibre walls thickness were measured between each of the zones of the oil palm trunk in relation to the different microwave treatment. All microwave treated samples showed changes in the fibre with the combinations of microwave treatment with 700 watts power intensities with 15 minutes exposure durations produced the most stretched and elongated fibres. This findings could be useful in finding suitable techniques for processing the OPT into value-added products.

This study evaluated the fibre morphology of Musa balbisiana leaf, stalk and stem portions for pulp and paper production. Samples of Musa balbisiana portions were prepared and macerated in equal volume of glacial acetic acid and hydrogen peroxide in ratio 1:1. Twenty cellulose fibres from each portion were randomly selected using Reichert visopan microscope to determine the physical fibre morphology while the derived fibre indices were calculated. Data collected were subjected to one way Analysis of Variance (ANOVA). Follow up tests carried out using Duncan Multiple Range Test (DMRT). Results showed that means of fibre length, fibre diameter, cell wall thickness and lumen width ranged between 1.35 and 2.46 mm, 16.46 and 33.34 µm, 7.58 and 24.99 µm, and 3.54 and 3.56 µm, respectively. The mean values of fibre length of Musa balbisiana leaf and stalk were not significant but were significantly different from the mean values of the stem at p<0.05. The mean values of felting rate, elasticity coefficient, rigidity coefficient, Runkel ratio and F factor ranged from 84.47 to 142.43, 48.94 to 76.07%, 11.96 to 25.53%, 0.34 to 1.12 and 433.50 to 627.22, respectively. The leaf stalk of Musa balbisiana had the best Runkel ratio of 0.34 while Musa balbisiana stem had the best fibre length of 2.46 mm. Results further showed that while fibre length of stalk and stem portions of Musa balbisiana were long fibres, the leaf portion was short fibre. Runkel ratios of Musa balbisiana stalk, Leaf and stem were very good, good and poor, respectively while the Leaf, stalk and stem were elastic, high elastic and rigid fibre, respectively. In conclusion, Musa balbisiana has proved to be a very suitable non-wood, agricultural based material for pulp and paper production.

High demand for wooden materials and rises in agricultural areas and forest fires increased the importance of composite particleboard instead of using solid woods. Particleboards are among the most popular materials used in interior and exterior applications. The objective of this study was to examine the physical and mechanical properties of phenol formaldehyde particleboard made from oil palm trunk (OPT) with 11% resin content. Two different board thicknesses were use; 12mm and 16mm. The particle size use in this study was 2mm and 1mm. Phenol formaldehyde (PF) was used as the binder. The result showed that modulus of rupture and modulus of elasticity were perform better at 16mm board thickness with 1.0mm particle size and meet the standard. The internal bonding strength was parallel with bending strength.

This study was conducted to develop the method of extracting beta-glucan from the fiber of Elaeis guineensis or oil palm trunk (OPT) and to evaluate its potential. From the previous studies, beta-glucan usually extracted from barley, oats and also bacteria. In this research, wet separation method which is also known as aqueous alcohol method was used to extract beta-glucan from the oil palm trunk fiber. This indirect method of producing beta-glucan was found optimized at conditions of 50% of ethanol as solvent, 4 hours pretreatment duration and temperature of 70ºC. Finally beta-glucan was analyzed by enzymatic method and the percentage of beta-glucan extracted in this study was 34.17 percent.

Oil Palm Trunk (OPT) act as a filler for polymer foam composite has been investigated and proved to have ability to absorb sound. In this study, treatment of wood untreated and treated with acid hydrolysis named as UP5 and TP5 was use as filler. This study was developed to compare the ability of sound absorption based on different composition of filler in polymer foam composite. By choosing the size of <500 µm, three different percentage has been selected which is 10 %, 15 % and 20 % for both conditions. These samples has been tested by using Impedance Tube test according to ASTM E-1050 for sound absorption coefficient, α measurement and Scanning Electron Microscopy (SEM) for determine the porosity for each  samples. 20 % filler loading of UP5 gives highest sound absorption coefficient of 0.97 at 4728 Hz. Meanwhile for 20 % loaded of TP5 gives 0.99 at 3371 Hz. When comparing the sound absorption coefficient for both sounds absorbing materials, TP5 polymer foam composite showed higher value of sound absorption coefficient, α at lower frequency level (Hz) as compared to UP5 polymer foam composite which gives better results in sound absorption.
